Implementation Reference
- server_tools.py:170-178 (handler)Handler function decorated with @joern_mcp.tool() that implements the tool by querying the Joern server remotely for the referenced method full name given a call ID and extracting the result.@joern_mcp.tool() def get_referenced_method_full_name_by_call_id(call_id:str) -> str: """Get the method info by the call id which the call is referenced the method @param id: The id of the call @return: The method info of the call """ response = joern_remote(f'get_referenced_method_full_name_by_call_id("{call_id}")') return extract_value(response)
